Great photos Matthew of two generations of Sydney tram in blue. It's great that you have a Variotram preserved.
2107 has been moved to the running shed so that it's near the pit - work is starting on reprofiling the wheels. A complex job, as it has to be done 'in situ', but thanks to Transport Heritage NSW, this is now moving forward.
2107 moved from the storage shed to the running shed pit road under it's own power. It's pretty well completely operational. There are 'nagglies' which probably come down to lack of use more than anything else, but it can move about on it's own.
2001 is being restored to be an example of a 'post war R1'. The Variotram was the next type of Sydney tram after the post war R1 variant.
If the Sydney trams had not totally closed (say the La Perouse route core down ANZAC parade had survived) I wonder if the post war R1s would have made it to 1997...
